[FEATURE REQUEST]: shebang for `fcs.py`

[schellt]

Is this a feature request for FCS-adaptor or FCS-GX? This is a feature request for FCS-GX.

Describe the problem you'd like to be solved After making fcs.py executable, running the script directly, instead of python3 fcs.py (as in the wiki) causes an error. It would be more convenient if the shebang would be already present.

Describe the solution you'd like Add #!/usr/bin/env python3 as the first line in fcs.py.

Describe alternatives you've considered No alternatives considered.
